It's inherently classist. Only those with access to moderately high levels of technology can spend or receive it. Only those with access to exceedingly high levels of technology can "mine" it. Heterosexual, middle class or higher white males are disproportionally represented in the demographics of bitcoin users. Bitcoin only serves to uphold the current kyriarchal socioeconomic structures by making sure the privileged become more privileged.
How do you know the sexuality of bitcoin users?
Well, I sure he just always seeing a lot of males is appearing in a lot of bitcoin project for advertising, introducing and another like that. In my opinions, the bitcoin users are dominated by the male gender.

I do not think so. Because I do see many many bitcoin projects are aiming women and having women as their brand ambassador. But that may be local to my country. But internationally too, we have a common practice of having women models for any product as it will target both the genders with obvious reasons. Hope this trend will change for a better future of bitcoin particularly to stop people boycotting any more.
